Description

Eye-drop packaging bottle

Technical field

This utility model belongs to eye-drop packaging bottle field.

Background technology

Existing eyedrops bottle mostly uses the bottle of plastic material, makes medicament for the eyes by finger pressing bottle body side surface during use Water oozes from the minim pipette being connected to bottle opening part.But due to the bad control of dynamics size of extrusion bottle, may once squeeze Going out many and make part collyrium overflow eyes, the consumption that additionally some collyrium is each must control within the specific limits, when The collyrium of instillation eyes may have side effects time too much, and eyes are produced unexpected injury.

Utility model content

Technical problem to be solved in the utility model is: the deficiency existed for prior art, it is provided that one can be determined Amount oozes the eye-drop packaging bottle of collyrium.

The deficiency existed for prior art, it is provided that eye-drop packaging bottle, including cylindrical bottle, the front end of bottle becomes Type has minim pipette, is arranged with a bottle cap outside minim pipette；

Described piston rod outer wall forms external screw thread；Described piston rod forms unidirectional promotion groove along its length；Described Bottle rear end is fixedly connected with a nut piece；Described nut piece upper end forms grafting circle, and nut piece is connect by grafting snare There is bowl cover；

Described nut piece inwall forms the female thread being connected with described external screw thread；

Described nut piece external wall of upper portion forms the promotion groove arranged along nut piece tangential direction；Slide in described promotion groove Connect and have pushing block assembly；Described pushing block assembly includes the pushing block being slidably connected with pushing block groove, in order to promote unidirectional promotion groove Elastic plate, and with described pushing block, end, one end connecting plate that is connected of one of elastic plate；Described elastic plate is away from connection One end of plate bends to piston rod direction, leaves spacing between described pushing block and elastic plate；The side of the opposing elastic plate of described pushing block Face forms trapezoidal by indent；Described by the briquetting slidably connecting and pressing slot fit in indent；Described briquetting upper end Face forms the pressing plate avoiding briquetting downslide to come off；Described promotion groove forms and described pressing along female thread tangential direction The strip shape gob that block coordinates；Described pressing plate lower end has to be avoided slipping on press component from by the spacing head of indent；

Form, in described promotion groove, the elastic plate passed for elastic plate to import and export；

Described pushing block is at end face two springs of fixing connection away from push pedal.

Compared with prior art, the beneficial effects of the utility model are: press pressing plate every time, and pressing plate is to moving down Promote pushing block assembly to move forward while Dong, make elastic plate pass elastic plate and import and export, act on unidirectional promotion groove, thus live Stopper rod rotates a smaller angle so that piston body moves down certain distance, and the collyrium stored in making bottle flows out one just The amount dripped, meanwhile, unclamps push pedal, and under the effect of spring force, pushing block assembly outwards ejects, and drives elastic plate in nut piece Slide in and out, make press component upward sliding.Again because the existence of spacing head, make pushing component will not go up slippage from pressing Groove.

Detailed description of the invention

Below according to accompanying drawing, detailed description of the invention of the present utility model is made a detailed explanation.

According to shown in Fig. 1 to Fig. 8, the eye-drop packaging bottle described in the present embodiment, including cylindrical bottle 2, bottle Front end forms minim pipette 21, is arranged with a bottle cap 1 outside minim pipette.

Described bottle open rearward end, slidably connects piston component 4 in bottle.

Described piston component includes the piston body 41 being slidably connected with bottle inwall, and is connected to piston body rear end Cylindrical piston rod 42.

Described piston rod outer wall forms external screw thread 421；Described piston rod forms unidirectional promotion groove along its length 422；Described bottle rear end is fixedly connected with a nut piece 3；Described nut piece upper end forms grafting circle 34, and nut piece passes through Grafting snare is connected to bowl cover 7.

Described nut piece inwall forms the female thread 31 being connected with described external screw thread.

Described nut piece outer wall lower end forms plural dop 32, described bottle side wall form with described in each Dop coordinates the bayonet socket 22 of clamping.

Described nut piece external wall of upper portion forms the promotion groove 33 arranged along nut piece tangential direction；Slide in described promotion groove Be dynamically connected pushing block assembly 5；Described pushing block assembly includes the pushing block 51 being slidably connected with pushing block groove, in order to promote one-way pushing The elastic plate 52 of dynamic groove, and the connecting plate 53 being connected with end, one end one of described pushing block, elastic plate；Described elastic plate One end away from connecting plate bends to piston rod direction, leaves spacing between described pushing block and elastic plate；The opposing bullet of described pushing block The side of property plate forms trapezoidal by indent 511；Described by slidably connecting and press the briquetting 63 of slot fit in indent, institute State briquetting with trapezoidal have a pair by indent coordinate the inclined-plane being slidably connected, formed between described inclined-plane and bottle length direction The angle of 20-40 degree；Described briquetting upper surface forms the pressing plate 61 avoiding briquetting downslide to come off；Described promotion groove edge Female thread tangential direction forms the strip shape gob 332 coordinated with described briquetting；Pressing group is avoided in described pressing plate lower end Slip on part from by spacing 63 of indent.

Form, in described promotion groove, the elastic plate passed for elastic plate and import and export 333.

Described pushing block is at end face two springs 331 of fixing connection away from push pedal.

Pressing pressing plate, pressing plate promotes pushing block assembly to move forward while moving down, and makes elastic plate wear every time Cross elastic plate to import and export, act on unidirectional promotion groove, thus piston rod rotation one smaller angle so that piston body moves down one Set a distance, the collyrium stored in making bottle just flows out the amount of, meanwhile, unclamps push pedal, under the effect of spring force, Pushing block assembly outwards ejects, and drives elastic plate to slide in and out in nut piece, makes press component upward sliding.Again because of position-limited groove Existence, make pushing component will not go up slippage from by indent.By such structure, even the inflexible old people of finger Use is convenient to.Described bottle and lid all can be easily manufactured respectively by integrally moulded, low cost.
